Supply original MC14016BDG, Interface - Analog Switches, Multiplexers, Demultiplexers, by ON Semiconductor

Quad Analog Switch/Quad Multiplexer
The MC14016B quad bilateral switch is constructed with MOS P−channel and N−channel enhancement mode devices in a single monolithic structure. Each MC14016B consists of four independent switches capable of controlling either digital or analog signals.
The quad bilateral switch is used in signal gating, chopper, modulator, demodulator and CMOS logic implementation.
Features
•Diode Protection on All Inputs
•Supply Voltage Range = 3.0 Vdc to 18 Vdc
•Linearized Transfer Characteristics
•Low Noise −12 nV/√Cycle, f ≥1.0 kHz typical
•Pin−for−Pin Replacements for CD4016B, CD4066B (Note improved transfer characteristic design causes more parasitic coupling capacitance than CD4016)
•For Lower RON, Use
The HC4016 High−Speed CMOS Device or
The MC14066B
•This Device Has Inputs and Outputs Which Do Not Have ESD Protection. Antistatic Precautions Must Be Taken.
